FOG-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 361,776, dated April 26, 1887. Application filed January 29, 1887. vSerial No. 225,9;24. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN A. N oEoRoss, of the town of Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Steam Fog-Signals, of which the following is a specification.

This invention relates to signals to be used by steam or sailing vessels in foggy weather; audit consists of a steam-Whistle device of a peculiar construction connected with an independent operating mechanism, whereby an au tomatic instrument is provided for uttering the signal sounds at stated intervals.

My signaling mechanism is constructed, coinbined, and arranged to operate substantially as hereinafter fully described, and pointed out in the claims.

In theaccompanying drawings, Figure l is a perspective view of my improved signaling device. Fig. 2 is atop or planview ofthe same. Fig. 3 is a sectional view of the valve mechan- Fig.4 is a face view of valve-seat,

` showing the holes which lead into the/whistlewhich it is secured to pipe and the mechanism closing one or two of said holes.

A represents a base or bed plate, which ports all the working parts. said bed-plate is placed a pillow-block, B, having journal-box supporting one end of a shaft, C, and on said shaft is provided a worm-gear pinion, D, and beneathsaid pinion isa countershaft, E, having a worm operating said pinion. Said shaft E is supported in bearings ce, fixed in a part of the said pillow-block B.

Fis an oscillating engine supported upon the bed-plate A, and is connected with the crank-diskf on the shaft E, and comprises the motive power for giving motion to the said shafts, steam being applied by means of pipe I from any steam-generator.

G is a chambered disk having flanges g g, by the bed-plate by bolts, or otherwise. Toits central part is provided a bearing for the shaft C, having a stuiiing-box, c, for making a tight j oint. To the end of shaft C is attached a rotating disk, H, fitted to closely lill the chamber of the disk G, and to rotate therein, and said rotating disk H is inclosed steamtight within the said chamber by a cap, K, screwed or bolted onto said disk G. The face of disk H toward the cover or cap K has sup- At one end ofan annular groove, h, forming a steam-space, into which steam is led by a pipe, J, fixed 1n the cap, as shown. To the disk G is also in ade a boss or projection, M, having a chamber, into which three or any suitable number of holes, m m m, through the back wall of the chamber, lead, and/from the said boss or projection arlses a pipe, P, to .which is connected a signal consisting of a steam-Whistle, O. Through the rotating disk H is made a hole, h', connected with the aforesaid steam-groove 71, and also 1n such location that said holeh will register with the holes m m m as said disk revolves, therebyr intermittently opening and closing communication'between said steam-chamber h and the chamber in boss or projection M, the purpose of which is to cause rapid successive sounds of the whistle at stated intervals. as the said disk H revolves.

A device for shutting off one or more of the holes m m m, consisting of a pin or spindle, N, is set in a transverse bore in the back wall of disk G, said pin projecting outward and provided with a stuffing-box, to prevent leakage. 'Ihe outer end of the pin is connected by joint with a hand lever, R, by which it maybe moved in or out, the inner end being intended to stop one or more of the said holes m, whereby the number of successive sounds of the whistle may be governed.

' Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, substantially as described, of a chambered disk inclosed with a cap supported on a suitable bed-plate, and having a central packed bearing for one end of a shaft carrying a rotating disk rotating Within said chambered disk, and provided4 with a steam-passage to intermittently open communication between an annular chamber or groove inthe face of said rotary disk, and ports in the back wall of the chambered disk leading to the whistle-pipe during the revolutions of said ro- 9 5 tating disk.

2. The combination, substantially as described, of a chambered disk inclosed with a cap and supported on a suitable bed-plate or foundation, and having a central packed bearing for one end of a shaft carrying a rotating disk rotating within said chambered disk, and

ICO

lshaft carrying a rotating disk, and provided through it communicatwith a steam-passage ing with an annular chamber or groove in the face of said rotating disk, and ports in the back Wall of said chambered disk leading to the whistle-pipe, and a pin or spindle Working in a counterbore for controlling said ports, the shaft being propelled by means of a Worm-gear connected with and operated by an engine, substantially in the manner and for the purpose specified.
